TECHNICAL FIELD

[0001] The utility model relates to a kind of construction equipment of building, specifically, a kind of construction device of filling column pile for air film. BACKGROUND

[0002] Air film structure is widely used in temporary exhibition hall, stadium, warehousing facilities and other places due to its light weight, quick erection and easy disassembly. However, the stability of the air film structure depends largely on its foundation, i.e. the stability and load-bearing capacity of the filling column pile.

[0003] The construction method of filling column pile usually includes drilling, placing steel reinforcement cage, and pouring concrete. When placing the steel reinforcement cage, it is necessary to ensure the manufacturing quality and overall perpendicularity of the steel reinforcement cage. However, in current construction, the perpendicularity of the steel reinforcement cage often deviates, and for this phenomenon, the steel reinforcement cage needs to be adjusted multiple times, or even needs to be lifted out and lowered again. Multiple adjustments greatly increase the construction time and make it difficult to guarantee the construction quality. SUMMARY

[0004] The utility model is just based on the above technical problem, and proposes a construction device of filling column pile for air film.

The pile tip is arranged at the lower end of the sinking pipe. The steel reinforcement cage is a cylindrical structure composed of vertical main reinforcement and transverse stirrup. The steel reinforcement cage is arranged in the sinking pipe and its lower end is in contact with the pile tip. A conical groove is arranged at the center of the top of the pile tip. A ring-shaped groove is arranged outside the conical groove. A plummet is arranged at the lower end of the steel reinforcement cage. The lower part of the plummet is a cone that matches the conical groove. The plummet is inserted into the conical groove. The plummet is provided with a side wing, and the side wing is connected with the steel reinforcement cage. The lower part of the steel reinforcement cage is inserted into the ring-shaped groove. A plurality of support members are arranged on the side wall of the steel reinforcement cage in a circumferential distribution. The outer end of the support member is in contact with the inner wall of the sinking pipe.

[0006] Preferably, the upper end of the ring-shaped groove is a trumpet-shaped inclined groove that opens outward.

[0007] Preferably, the edge of the side wing is provided with a half-opened bayonet, and the main reinforcement is clamped in the bayonet and fixed by spot welding.

[0008] Preferably, the support is installed at the joint of the stirrup and the main reinforcement, the support comprises a clamping seat and a roller located at the front side of the clamping seat, a transverse clamping groove and a vertical clamping groove are arranged in the middle of the clamping seat, the main reinforcement is clamped into the vertical clamping groove, the stirrup is clamped in the transverse clamping groove, and two buckle plates are further arranged at the rear side of the clamping seat, one end of the buckle plate is hinged to the two sides of the rear side of the clamping seat, and the other end of the buckle plate is buckled on the clamping seat.

[0009] Preferably, the plummet disc is an iron disc.

[0010] Beneficial effects: when the construction device lowers the reinforcement cage, the iron plummet disc is used as a plummet to reduce the swing of the reinforcement cage, the cone at the lower side of the plummet disc can slide to the middle of the pile tip after contacting the conical groove, thereby ensuring that the reinforcement cage is installed vertically and correctly; meanwhile, the support located at the side of the reinforcement cage can roll and limit on the inner wall of the sinking pipe, further ensuring that the reinforcement cage is installed correctly.
